There is much to be learned by a study of N6LF's excellent work on
radials. It's a combination of modeling and careful measurement of real
antennas.
I've done talks at Pacificon and for various ham clubs about getting on
160M, and about 90% of it is about radial systems and antennas. It
summarizes material in the ARRL Antenna Book, work by N6LF and K3LC,
W8JI, and K2AV.

Larry,OMs and YLs,
Your point is correct some of the antenna books are very vague on this
point but I have seen it reinforced on the Top Band Reflector. Generally
Qty 120 one hundred ten foot radials would be more than adequate for full
performance and of course 110 feet is less that a even 0.25 wavelength on
160 meters let alone 0.4 wavelength.
